Tiangou Mountain is the highest point of Xiaoyu, and the top of the mountain overlooks the city, and the night scenery is particularly spectacular. The cable car takes 4 minutes to reach the top of the mountain. The rooftop observation deck on the top of the mountain is the best location to overlook the city of Otaru. There are also three other observation decks around, which can overlook the Otaru from different angles. Behind the cable car is a statue of a long-nosed Tiangou. It is said that touching its long nose can eliminate evil and fulfill its wish. The beautiful snow scene of Tiangou Mountain is also the location of the classic movie "Love Letter". The back of the film Watanabe Bozi is filmed on Tiangou Mountain.
